     26=== Massive-MIMO Antennas ===
     27
     28The top of each Massive-MIMO mini-rack is populated with a horizontal array of 32 [attachment:APAMSJ-137.pdf antennas]. They are mounted on a rectangular plate with a 2 inch spaced grid pattern. The antenna locations correspond to the physical RF port locations of the USRPs to which they are attached (see table below).
